Statistical analysis of gender and mindset group differences…

SPSS HOMEWORK: VARIABILITY TEMPLATE Problem Set 1: The following data are based on numbers taken from the Bureau of Labor Statistics surveys from the year 2019 (located as a resource on the assignment page in Canvas), for community, service, social science, and education occupations. They represent the average weekly pay for wage and salary earners measured during 2019 and broken down by gender. Enter these data into a new file containing one grouping variable for gender and one variable for salary. For the Gender variable in column 1, code women as 1 and men as 2 Remember to define these in Value Labels as covered in the presentations. There will be thirteen 1s and thirteen 2s (as many participants as in each group) in the Gender column in SPSS. The corresponding earnings will be entered in the Salary column in SPSS. Remember to put your initials within any and all variable names. Women Men 1212 1042 1095 942 579 1015 944 890 896 556 741 664 554 1870 1161 1262 1190 707 1423 1108 1155 501 1694 953 890 671 1. Using the data in the table above, set up your data file in SPSS and create one table of Descriptive Statistics using the Explore function that shows descriptives for salary split by group (Women and Men separately). Paste the table here: (8 pts) 2. What are the mean and standard deviation of salaries for women? (5 pts) PSYC 354 Page 2 of 3 3. Find the values for skewness in the table. What kind of skew is present for each group? (5 pts) 4. Using the same data, create a boxplot in SPSS to show the difference in salaries between women and men. Paste the boxplot here: (6 pts) 5. Based on the boxplot and descriptive statistics, which group shows more variability in salary? Support your answer with knowledge from the presentations and/or reading from this week. (6 pts) Problem Set 2: A school psychologist wants to examine the difference in the minutes that middle school students spend working on a difficult math problem depending on whether they have been primed with a statement reflecting a fixed mindset or one reflecting a growth mindset. She divides her students into two groups: one is primed with the statement that Some people are just better at math (fixed mindset), while the other group is primed with the statement that People can improve in math with hard work (growth mindset) She records the number of minutes each student works on the math problem in the table below. She assigns values to the Mindset Group variable as follows: 1 = Fixed; 2 = Growth. Remember to put your initials within any and all variable names. Mindset Group (1 = Fixed; 2 = Growth) Minutes Spent on Difficult Math Problem 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 1.5 1.2 1.9 1.8 0.6 1.4 3.7 0.9 0.7 2.1 2.8 1.8 1.3 2.4 4.6 3.5 2.2 1.4 3.3 PSYC 354 Page 3 of 3 1. Using the data in the table above, set up a data file in SPSS and create one table of descriptive statistics using the Explore command that is split by Mindset group. Paste the table here: (8 pts) 2. Compare the means of the two groups. Which group worked longer on average on the difficult math problem? (4 pts) 3. Using the same data, create a paneled histogram to show the distribution of minutes spent working on the problem in each sample. Paste the histogram here: (7 pts) 4. Based on the histogram and Explore table of descriptive statistics, are these distributions symmetrical or skewed? If skewed, what kind of skew is present? Support your answer with the appropriate data. (5 pts) 5. Based on the data, what might the school psychologist conclude about the effect of mindset statements on students effort levels in solving difficult math problems? Answer in 2-3 complete sentences.
